Abstract
The amounts of Co-PCB emission in Tokyo Bay basin were estimated using a multimedia environmental model, the CoZMo-POP model, which was developed for describing the long-term fate of persistent organic pollutatnts (POPs) in a coastal environment. The Co-PCB concentrations in sediment estimated using the model effectively explained the chronological changes in the concentrations in substances that settled at the bottom of sea water, which were estimated by a sediment mixing model based on the concentrations in sediment core samples. Furthermore, the estimated chronological changes in the amounts of Co-PCB emission in each year were in agreement with the chronological changes in PCB demand in Japan.
